Hi Martin,

Seeing my response in print it looks a bit terse - I must have been
associating with Harlan too much <g

I did not mean to put your formula down, I was just in a bit of a rush when
I wrote it. Your formula does satisfy the OP's requirements as stated with
no double digit numbers given.

My apologies, it was not meant that way.
