The densest packing of 13 congruent circles in a circle

Ferenc Fodor

Feherviz u. 26, IV/13, H-2000 Szentendre, Hungary

Abstract: The densest packings of $n$ congruent circles in a circle are known for $n\leq 12$ and $n=19$. In this article we examine the case of $13$ congruent circles. We show that the optimal configurations are identical to Kravitz's conjecture. We use a technique developed from a method of Bateman and Erdos, which proved fruitful in investigating the cases $n=12$ and $19$.

Keywords: circle packing, density, optimal packing

Classification (MSC2000): 52C15
