Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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