 * The main service s in the served 112  (namely, sub levels 5, 3, 2 and 1, service level, and floors 1-7 and 9-108).
 * It is also the.
 * There are 4×(2×8-2) + 6×(8+3) = 122 buttons in the  building in.
 * There are 135 nominal frequencies (n × 9, where 17 <= n <= 31 or 59 <= n <= 178) in , and the bandwidth of the  band is 135 kHz.
 * 136 is the number of floors (namely, concourse, ground and 1 to 138; 41, 74, 110 and 137 have been skipped) served by the main service elevator in the.

 * Furthermore, the of s is limited to 148.
 * Finally, section 148 of the provides punishment for listening to  and  by third parties.
 * The is the first, which is neither an Egyptian pyramid nor a church building. Its elevator has a rise of 152.21 metres.
 * The first carrier frequency in the band is at 153.
 * In China, the starts at 167.
 * There are 194 different s, for which the to   conversion, as used in, leads to.
 * In most of, there are 204 nominal frequencies (n × 0.1 , where 876 <= n <= 1079).
 * It is also the number of s in a with.
 * In some countries, such as, there are 205 nominal CCIR frequencies (n × 0.1 MHz, where 875 <= n <= 1,079).
 * The in many countries is 220 s.
 * In some countries, such as, the ends at 223.
 * It is also the number of non-control 8-bit characters.
 * The in some countries is 240 s.
 * There are 306 channels in the German 80 MHz band.
 * The was 435, but it has been raised to 440.
 * In some countries, formerly used 441 s.
 * There are 480 visible scan lines in in most of the.
 * The Burj Khalifa is the in the world. Its main service elevator has a rise of 504.2 metres.
 * In most of the Americas, used 525 scan lines.
 * It is also the lower edge of the radio band (in kHz).
 * television has 540 visible scan lines.
 * It is also the number of channels in the German 80 MHz and 160 MHz bands.
 * In most of the, has 576 visible scan lines.
 * The is the highest building in China. Its main service elevator has a rise of 578.5 metres.
 * A common weight rating for elevators was 600 kilograms, but it has been increased to 630, except for Japan and South Korea.
 * It is (or was) also a common step width (in millimeters) for escalators; the other ones are 800, 1,000 and sometimes 900.
 * There are 614 grid points on a with a 10° net.
 * In most of the Old World, analog television used 625 scan lines.
 * The of s is limited to 660.
 * In the, the 700 MHz uplink band starts at 703.
 * Some services have 704 s in a scan line.
 * In, the UHF TV band ends at 710.
 * Some services have 720 visible scan lines.
 * It is also the number of s in a standard-definition television scan line.
 * In some countries, analog television formerly used 819 scan lines.
 * Some services have 1,080 visible s.
 * It is also the bandwidth (in ) of the in most countries of the world.
 * The last carrier frequency in the radio band is at 1,602  in the.
 * Some s produced in the and, such as the  and the , have problems with their digital s, if they reach the number 300,000.
 * The is the fastest supercomputer in the world; it has 10,649,600 cores.
 * With 19,860,000 cores, the has more cores than any other supercomputer in the world.
