A Family of Codes With Locality Containing Optimal Codes

Locally recoverable codes were introduced by Gopalan
et al.
in 2012, and in the same year Prakash
et al.
introduced the concept of codes with locality, which are a type of locally recoverable codes. In this work we introduce a new family of codes with locality, which are subcodes of a certain family of evaluation codes. We determine the dimension of these codes, and also bounds for the minimum distance. We present the true values of the minimum distance in special cases, and also show that some elements of this family are “optimal codes”, as defined by Prakash
et al.
