Presentation

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

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

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