We report evidence for the decay mode B→ϕϕK based on an analysis of 78 fb-1 of data collected with the Belle detector at KEKB. This is the first example of a b→ss̅ ss̅ s transition. The branching fraction for this decay is measured to be B(B±→ϕϕK±)=(2.6-0.9+1.1±0.3)×10-6 for a ϕϕ invariant mass below 2.85 GeV/c2. Results for other related charmonium decay modes are also reported.
