There is a simple formula for the absolute value of the determinant of the character table of the symmetric group Sn. It equals aP, the product of all parts of all partitions of n (see [4, Corollary 6.5]). In this paper we calculate the absolute values of the determinants of certain submatrices of the character table X of the alternating group An, including that of X itself (Section 2). We also study explicitly the powers of 2 occurring in these determinants using generating functions (Section 3).
