Hi all: I am doing some homespun research relative to the

distribution of primes and am in need of some help on two items.

Question 1: Is there a published reference for the "mirror

sequence" as it relates to the distribution of a finite set (3,5,7

for example)of divisors along the full set of odd numbers

1,3,5,7,9,11. . . to any odd k? I have googled around and done a

university library search and found nothing. I understand the mirror

sequence is used extensively in primality testing, so hopefully

someone here can point me toward a reference.

Question 2: Is there a way to determine if the function "6n+11" ever

forms a perfect square for some n (n=1,2,3,4 etc to any m), other

than trial and error? I have tried a few thousand n's with negative

results, but thought I'd ask if there is a better way before I do a

more exhaustive check.

Thanks for your consideration. Bill
