Presentation

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

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

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

Polycyclic presentation:
