  Transmission of a vertex v of a connected graph G is the sum of distances
from v to all other vertices in G. Graph G is transmission irregular (TI) if no
two of its vertices have the same transmission, and G is interval transmission
irregular (ITI) if it is TI and the vertex transmissions of G form a sequence
of consecutive integers. Here we give a positive answer to the question of
Dobrynin [Appl Math Comput 340 (2019), 1-4] of whether infinite families of ITI
graphs exist.
