Presentation

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

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

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