Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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