Going Cyclic With Geometric II (Posted on 2009-07-04)

Three 3-digit non leading zero positive base N integers P, Q and R, with P > Q > R, are such that:

Q is the geometric mean of P and R, and:
P, Q and R can be derived from one another by cyclic permutation of digits.

Determine all possible positive integer values of N < 30 for which this is possible.
