A number pyramid (Posted on 2012-05-18) Difficulty: 2 of 5
Divide a set of 10 distinct digits into 4 subsets, each containing a different number of digits, adhering to the following conditions:

Two sets contain digits that can form a reversible prime, in the third set one can create a reversible square number and the remaining set has exactly one member twice as big as another.

Obeying the above restrictions do we get two distinct solutions - as I hope - or more?
