 Palindromic and Tautonymic III (Posted on 2010-03-23)
Make a list of distinct positive integers that are obtained by assigning a different base ten digit from 1 to 9 to each of the capital letters in this expression.

(A+B)*C + (D–E)/F + (GH)*I

What are the respective minimum and maximum positive palindromes from amongst the elements that correspond to the foregoing list?

As a bonus, what are the respective minimum and maximum positive tautonymic numbers that are included in the list? How about the respective maximum and minimum prime numbers?

So far I have limited h < 4 (to keep test size down).

I find 882 assignments which yield 3-digit palindromes (no leading zero).  68 of these yield 101:minimum; 4 yield 979:maximum.  Will expand the test.
