function tickSpacing() external view returns (int24)

The pool tick spacing

Ticks can only be used at multiples of this value, minimum of 1 and always positive e.g.: a tickSpacing of 3 means ticks can be initialized every 3rd tick, i.e., ..., -6, -3, 0, 3, 6, ... This value is an int24 to avoid casting even though it is always positive.

[0]	int24	The tick spacing

maxLiquidityPerTick (0x70cf754a)

function maxLiquidityPerTick() external view returns (uint128)

This parameter is enforced per tick to prevent liquidity from overflowing a uint128 at any point, and also prevents out-of-range liquidity from being used to prevent adding in-range liquidity to a pool

Return values:

Name	Type	Description
[0]	uint128	The max amount of liquidity per tick
