Lua Help to return various random positions

[Syl4s]

I would like help to return several positions below this function currently it only returns 1

function randomSquare2x2(pos)
    local position = {
        -- 9, 10, 11, 12, 13
        -- 14, 01, 02 03, 15
        -- 16, 04, 00, 05, 17 -- 00 is player
        -- 18, 06, 07, 08, 19
        -- 20, 21, 22, 23, 24
    Position(pos.x - 1, pos.y - 1, pos.z), -- 1       
    Position(pos.x, pos.y - 1, pos.z), -- 2
    Position(pos.x + 1, pos.y - 1, pos.z), -- 3
    Position(pos.x - 1, pos.y, pos.z), -- 4       
    Position(pos.x + 1, pos.y, pos.z), -- 5       
    Position(pos.x - 1, pos.y + 1, pos.z), -- 6 
    Position(pos.x, pos.y + 1, pos.z), -- 7         
    Position(pos.x + 1, pos.y + 1, pos.z), -- 8       
    Position(pos.x - 2, pos.y - 2, pos.z), -- 9
    Position(pos.x - 1, pos.y - 2, pos.z), -- 10       
    Position(pos.x, pos.y - 2, pos.z), -- 11       
    Position(pos.x + 1, pos.y - 2, pos.z), -- 12       
    Position(pos.x + 2, pos.y - 2, pos.z), -- 13       
    Position(pos.x - 2, pos.y - 1, pos.z), -- 14
    Position(pos.x + 2, pos.y - 1, pos.z), -- 15       
    Position(pos.x - 2, pos.y, pos.z), -- 16       
    Position(pos.x + 2, pos.y, pos.z), -- 17
    Position(pos.x - 2, pos.y + 1, pos.z), -- 18
    Position(pos.x + 2, pos.y + 1, pos.z), -- 19
    Position(pos.x - 2, pos.y + 2, pos.z), -- 20
    Position(pos.x - 1, pos.y + 2, pos.z), -- 21
    Position(pos.x, pos.y + 2, pos.z), -- 22                           
    Position(pos.x + 1, pos.y + 2, pos.z), -- 23
    Position(pos.x + 2, pos.y + 2, pos.z) -- 24
    } 

    return position[math.random(1,24)]
end
