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