Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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