This group is defined as the external direct product of the following two groups:

  1. The group special linear group:SL(2,5) (order 120), which is also the double cover of alternating group:A5 (and also its Schur covering group).
  2. The group special linear group:SL(2,7) (order 336), which is also the double cover of PSL(3,2) (and also its Schur covering group).

Function Value Similar groups Explanation
order (number of elements, equivalently, cardinality or size of underlying set) 40320 groups with same order order of direct product is product of orders, so the order is 120 \times 336 = 40320
