Presentation

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

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

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