Presentation

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

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

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