  Consider the ensemble of real symmetric Toeplitz matrices whose entries are
i.i.d random variables chosen from a fixed probability distribution p of mean
0, variance 1 and finite higher moments. Previous work [BDJ,HM] showed that the
limiting spectral measures (the density of normalized eigenvalues) converge
weakly and almost surely to a universal distribution almost that of the
Gaussian, independent of p. The deficit from the Gaussian distribution is due
to obstructions to solutions of Diophantine equations and can be removed (see
[MMS]) by making the first row palindromic. In this paper, we study the case
where there is more than one palindrome in the first row of a real symmetric
Toeplitz matrix. Using the method of moments and an analysis of the resulting
Diophantine equations, we show that the moments of this ensemble converge to an
universal distribution with a fatter tail than any previously seen limiting
spectral measure.
