pm are considered, where p is a prime and m> 0 is any integer. The b-symbol distance for
prime power length, ie ps is also studied for any integer s> 0. The Hamming and symbol-pair
distances of all δ-constacyclic codes have been thoroughly studied in [18], where δ is an unit
in the ring F p m+ uF pm which is of the form ζ and φ+ uφ, where 0≠ 6 φ, φ, ζ∈ F p m. In this
paper, the b-symbol distance of all such δ-constacyclic codes of prime power length is …
