Abstract

A nonnegative integer nn is dd-translated unit sensitive when appending dd zeros to the right of the number and changing the unit digit to any possible unit digit (so long as the resulting number is not nn) results in a composite number. We find an arithmetic progression of nonnegative integers that are dd-translated unit sensitive for any nonnegative integer dd. We construct the arithmetic progression such that there exists kk consecutive primes in the progression for any positive integer kk. The first known prime that is dd-translated unit sensitive for any nonnegative integer dd is found as a consequence. We also refine the arithmetic progression such that the integers in the progression are dd-translated unit sensitive for any nonnegative integer dd and are Brier numbers. The refined arithmetic progression contains kk consecutive primes for any choice of positive integer kk.
