Presentation

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

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

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