Line 1:
===Incorrect===
 
Note that the table displayed on the task page is incorrect. Currently for the exponent for a ↑ 15a↑15 it has: (d←(b←a × a b←a×a) × b ×b) × d × d × a×d×d×a.
 
But this means b←a↑2 and d←a↑4 and the result calculated is a↑13 --[[User:Rdm|Rdm]] 15:04, 27 August 2011 (UTC)
 
I think it should be: d × d × d×d×(d ← a × b × d←a×b×(b ← a × a b←a×a)) but my preferred notation (where the operations are strictly right to left) conflicts with the format used in the table (where assignment is right to left but are used left to right).
 
=== Alternative "special objects" to using Matrices ===
