In mathematics, a group of 15 items is known as a quindecad. Some common items that come in groups of 15 include eggs in a carton, months in a quarter, and players on a Rugby team. Additionally, elements in the lanthanide series of the Periodic Table have atomic numbers that are multiples of 15.
Oh, what a delightful question! There are so many things that come in groups of 15. You might find 15 beautiful sunflowers swaying in a gentle breeze, or perhaps a dozen eggs with three more added for good measure. Nature is full of wonderful things that come in groups of 15, just waiting to bring a smile to your face.
