Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,4)(5,6)(7,8)(9,10)(11,12)(13,14,18,23)(15,20,26,27)(16,22,17,21)(19,24,28,25);(1,2,3,4)(13,15,17,24,18,26,16,25)(14,19,22,27,23,28,21,20);(6,8)(13,15)(14,20)(16,24)(17,25)(18,26)(19,21)(22,28)(23,27);(10,12)(13,16,18,17)(14,21,23,22)(15,24,26,25)(19,27,28,20)
