Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 5 generators on 28 points:

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