The number may seem to stop at 10^5 and 10^^2 and 10^^^2 and 10^^^^2 and 10{5}2 and 10{6}2 and 10{10... and 10{10{9... and a few more but also for a very long time at 10{{6... It really stops at 10{{10{10{10{10{10{10{10{9}10{8}10{7}10{6}10{5}10^^^^10^^^10^^10^(1.79e308) around 36 million seconds (more like 36 million and 8350) or ~416(21/30) days in. That's also around 10{{10{{7... or if you like san, s(10,s(10,7,1,1,2),1,1,2), s(a,b,1,1,2) means a{{b... if you were wondering.
