number of pepper plants for good pollination

I'm getting some spring fever and thinking about my garden for this year. I have limited space (three 4x8 raised beds) and like to have variety.
I like to grow peppers and in the past have planted varieties in groups of 6 plants. This yields more peppers than I need so I'd like to reduce the number of plants for each type.
From my research, it looks like peppers in general both self pollinate and cross pollinate. If I planted my peppers in groups of 3, should I still expect good yields from each plant? Is there a rule of thumb for how many plants are the minimum for good pollination?
Thanks

At least one. :-)
Seriously, don't worry about it. I've gotten heavy crops of peppers from 2 or 3 plants in a short row, and good crops from a single isolated pepper plant as long as it was planted outside where wind and insects could do their jobs.
