Let ε be a real number such that and t a positive integer. Let n be a sufficiently large positive integer as a function of t and ε. We show that every n‐vertex graph with at least n1+ε edges contains a subdivision of Kt in which each edge of Kt is subdivided less than 10/ε times. This refines the main result in [A. Kostochka and Pyber, Combinatorica 8 (1988), 83–86] and resolves an open question raised there. We also pose some questions. © 2010 Wiley Periodicals, Inc. J Graph Theory 67:139‐152, 2011
