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