....Output: A set and an action of G as required in Theorem 2.3. Call ALT ORDER. If G = A r for some r, call ALT1 and then ALT2. Let p be the prime contributing the largest prime power to jGj, except when jGj = jPSU(4; 2)j and n 6= 40, in which case let p = 2. Then p is the characteristic of G [Ar]. If p fi fi n call CLASSICAL NS (Section 5) producing a new set Omega 0 . Here Omega is a G orbit of nonsingular subspaces, and CLASSICAL NS produces the set Omega 0 of isotropic or singular points of an underlying vector space. Now p6 fi fi n. Call PSL ORDER (Section 4) If G = ....

Kantor and T. Penttila Suppose that the procedure determines that jGj = r =2 for some r. By [Ar], G is isomorphic to A r or PSL(3; 4) If jGj = jPSL(3; 4)j = jA 8 j then G = A 8 by Hypothesis 2.1(a,b) and the procedure correctly decides that G is not an alternating group.
