Presentation

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

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

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