Sorry if I misunderstood you but I'll reply just in case in order to save you possible extra work and confusion...

You said aaz to aba has a gap but you correctly noted a=0...z=25.
Therefore, aaz=(0*26^2 + 0*26 + 25)=25 and aba=(0*26^2 + 1*26 + 0)=26 - No gap. Likewise, azz=675 and baa=676. Again, no gap.

Hope this helps, sorry if I misunderstood.
