Abstract: This paper explores the structure of quasi-socle ideals I=Q:m^2 in a
Gorenstein local ring A, where Q is a parameter ideal and m is the maximal
ideal in A. The purpose is to answer the problem of when Q is a reduction of I
and when the associated graded ring G(I) = \bigoplus_{n \geq 0}I^n/I^{n+1} is
Cohen-Macaulay. Wild examples are explored.
