Looking at the BIP32 definition, I hit a line that I would= appreciate clarification on.

Under the s= ection "Private parent key =E2=86=92 private child key" there is = a step:

"The returned child key ki is p= arse256(IL) + kpar (mod n)."

Can someone help= me understand what "n" is in the context of this algorithm?=C2= =A0 I very well could be looking right at it, but wanted to double check if= I am missing something.

Thanks,
