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