No. of partitions in NDB cluster

Hi,

I am using NDB cluster 7.1. the configuration is as below,

- 6 NDB nodes
- using ndbmtd
- NoofReplicas = 2
- MaxNoOfExecutionThreads = 8

CREATE TABLE TxnLog (
`LID` varchar(255) NOT NULL,
`ACTIVE` char(1) DEFAULT NULL,
`NID` varchar(255) NOT NULL,
PRIMARY KEY (`LID`),
) ENGINE=ndbcluster


So I think there are 3 groups and 2 nodes for each group.
As there is no user-defined partitioning, so I think the No. of partitions should be 6, as same as No. of NDB nodes.

But when using 'explain partitinos ...', I found there are totally 24 partitions.

Why?
