Presentation

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

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

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