Hi.

Base 10 number 1344556 to

Base 77 number 2,72,59,59,

is correct in the meaning that I understand what you do. I have not seen any representation of these translation other than the obvioous 0,1,2,3,...a.b,..,f for the radix 16( I know there are others for bigger radises, but these are seldom used. I would think that [2,72,59,59]radix(77) could be a meaningfull notation ?
