Presentation

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

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

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