For instance while the OP_CHECKMULTISIG opcode can itself accept up to 20 pubkeys, with 33-byte compressed pubkeys it is only possible to spend a P2SH output requiring a maximum of 15 pubkeys to redeem: 3 bytes + 15 pubkeys * 34 bytes/pubkey = 513 bytes. +As a consequence of the requirement for backwards compatibility the serialized script is itself subject to the same rules as any other PUSHDATA operation, including the rule that no data greater than 520 bytes may be pushed to the stack.
