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