Popis: Let G be isomorphic to GL n ⁢ ( q ) {\mathrm{GL}_{n}(q)} , SL n ⁢ ( q ) {\mathrm{SL}_{n}(q)} , PGL n ⁢ ( q ) {\mathrm{PGL}_{n}(q)} or PSL n ⁢ ( q ) {\mathrm{PSL}_{n}(q)} , where q = 2 a {q=2^{a}} . If t is an involution lying in a G-conjugacy class X, then, for arbitrary n, we show that, as q becomes large, the proportion of elements of X which have odd order product with t tends to 1. Furthermore, for n at most 4, we give formulae for the number of elements in X which have odd order product with t, in terms of q.
