Section 3 says:
e. The rotate left (circular left shift) operation ROTL^n(x), where x is a w-bit word and n is an integer with 0 <= n < w, is defined by ROTL^n(X) = (x<<n) OR (x>>(w-n))
It should say:
e. The rotate left (circular left shift) operation ROTL^n(x), where x is a w-bit word and n is an integer with 0 <= n < w, is defined by ROTL^n(x) = (x<<n) OR (x>>(w-n))
Notes:
A typo. The function argument has to be x, not X.
