Presentation

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

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

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