I think you will find that Mr Kanadadai meant that where 2^x - 1 = y, the minimum universal exponent is the lowest positive x that makes y congruent to 0(mod 31), not 0(mod y).

I think this is a consequence of the corollary he mentioned in his previous post

I'm not saying I follow his argument, or even agree with him. I'm just offering to clarify what I think he said.
