Presentation

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

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

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