Child Play.. (Posted on 2009-08-07) Difficulty: 3 of 5
111111111....or maybe not! *

A version of "hopscotch" has this layout:

D G
A B C F
E H

Replace each of the letters with a unique digit from 0 to 9 such that you "hop" from one criterion to the next:
11111 AB is Prime,
11111 BCD is a Triangle,
11111 DEF is a Square and
11111 FGH is a Fibonacci number,
111111111111111 and none begin with a zero.

What 8-digit numbers are formed by this process?
What is significant about the highest and lowest?

* This can be logically deduced albeit a little time consuming.
