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