User blog:Alemagno12/BM3 has an infinite loop

First, I prove that (0,0,0)(1,1,1)(2,1,1)(1,1,1) is standard... ...and then I prove that it doesn't terminate:
 * (0,0,0,0)(1,1,1,1)
 * = (0,0,0)(1,1,1)(2,2,2)(3,3,3)(4,4,4)...
 * > (0,0,0)(1,1,1)(2,2,2)
 * = (0,0,0)(1,1,1)(2,2,1)(3,3,1)(4,4,1)...
 * > (0,0,0)(1,1,1)(2,2,1)
 * = (0,0,0)(1,1,1)(2,2,0)(3,3,1)(4,4,0)(5,5,1)...
 * > (0,0,0)(1,1,1)(2,2,0)
 * = (0,0,0)(1,1,1)(2,1,1)(3,1,1)(4,1,1)...
 * > (0,0,0)(1,1,1)(2,1,1)(3,1,1)
 * = (0,0,0)(1,1,1)(2,1,1)(3,1,0)(4,2,1)(5,1,1)(6,2,0)(7,3,1)(8,1,1)...
 * > (0,0,0)(1,1,1)(2,1,1)(3,1,0)
 * = (0,0,0)(1,1,1)(2,1,1)(3,0,0)(4,1,1)(5,1,1)(6,0,0)(7,1,1)(8,1,1)...
 * > (0,0,0)(1,1,1)(2,1,1)(3,0,0)
 * = (0,0,0)(1,1,1)(2,1,1)(2,1,1)(2,1,1)...
 * > (0,0,0)(1,1,1)(2,1,1)(2,1,1)
 * = (0,0,0)(1,1,1)(2,1,1)(2,1,0)(3,2,1)(4,1,1)(4,2,0)(5,3,1)(6,1,1)...
