Presentation

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

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

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