Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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