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