摘要：

Let C-n denote the cycle with n vertices, and. denote the graphs consisting of t copies of C-n with a vertex in common. Koh et al. conjectured that C-n((t)) is graceful if and only if nt equivalent to 0,3 (mod 4). The conjecture has been shown true for n = 3, 5, 6, 7, 9, 4k. In this paper, the conjecture is shown to be true for n = 11.
