Presentation

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

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

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