N2 - Let G be a finite group and p a prime number. We compute the Euler characteristicin the sense of Leinster for some categories of nonidentity p-subgroups of G. The p-subgroup categories considered include the Brown poset S G *, the transporter category T G *, the linking category L G *, the Frobenius, or fusion, category F G *, and the orbit category O G * of all nonidentity p-subgroups of G.
