Presentation

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

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

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