User blog comment:Alejandro Magno/Make an extension of the Notation! (my style)/@comment-5029411-20140925234703

To make extension 8, let change [a]b into [a][b].

(0[0][0][1]1)#n = (0[0][0[0][0[0][...]1]1]1)#n /w n nested

(0[0][0][2]1)#n = (0[0][0[0][0[0][...][1]1][1]1][1]1)#n /w n nested

(0[0][0][0][1]1)#n = (0[0][0][0[0][0][0[0][0][...]1]1]1)#n /w n nested

Limit is (0[0][0]...[0][1]1)#n.
