This is a first step in counting the number of multiple solutions in certain glassy random matrix models introduced by N. Deo [Phys. Rev. E 65, 056115 (2002)]. We are able to do this by reducing the problem of counting the multiple solutions to that of a moment problem. More precisely, we count the number of different moments when we introduce an asymmetry (tapping) in the random matrix model and then take it to vanish. It is shown here that the number of moments grows exponentially with respect to N, the size of the matrix. As these models map onto models of structural glasses in the high temperature phase (liquid), this may have interesting implications for the supercooled liquid phase in these spin glass models. Further, it is shown that the nature of the asymmetry (tapping) is crucial in finding the multiple solutions. This also clarifies some of the puzzles raised by E. Brézin and N. Deo [Phys. Rev. E 59, 3901 (1999)].
