I just checked : No, for 208, my data gives only 1 antecedent of order 1, it is 268, because 208 is not an antecedent of itself.

60^90 ends with a 56-digit prime number !
So it was just a coincidence, as I thought.
It will certainly be the same with 60^92.
You are brave and bold to tackle such sequences !
