I need help counting from 0-26 using onli 3 symbols like x, c, a without exceeding more than 3 symbols per num
x:2


c:1


a:0





three digits: _*9 _*3 _*1





for example: cxa=1*9+2*3+0*1=15


xxx=2*9+2*3+2*1= 26


a=0, c=1, x=2





In other words, this is a base 3 number system.


You can use this system to express 0-26.
