Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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