Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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