Presentation

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

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

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