Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 3 generators on 40 points:

(1,2,3,4)(5,6,8,7);(2,4)(9,10,11,16,12,17,19,28,13,18,20,29,22,30,31,38,14,15,21,25,23,26,32,35,24,27,33,36,34,37,39,40);(5,7,8,6)(10,15)(16,25)(17,26)(18,27)(28,35)(29,36)(30,37)(38,40)
