Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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