Claim 0:
1. A management system, comprising:
a plurality of power feed mats, wherein
each of the plurality of power feed mats is configured to wirelessly feed power to a movable body,
the plurality of power feed mats is configured to communicate among the plurality of power feed mats while the plurality of power feed mats is placed at a prescribed location,
each of the plurality of power feed mats includes a controller,
the plurality of power feed mats includes:
a subject mat;
a first adjacent mat configured to monitor the subject mat; and
a second adjacent mat configured to be monitored by the subject mat,

the subject mat is configured to,
in response to receiving a presence confirmation notification from the first adjacent mat while being present at the prescribed location, send a presence signal back to the first adjacent mat, the presence signal being a signal indicating that the subject mat is present at the prescribed location,
in response to receiving the presence confirmation notification from the first adjacent mat while being not present at the prescribed location, not send the presence signal back to the first adjacent mat,
transmit a presence confirmation notification to the second adjacent mat, and
in response to not receiving the presence signal from the second adjacent mat even when a time elapsed since transmission of the presence confirmation notification to the second adjacent mat by the subject mat has exceeded a prescribed value, perform, through the controller, prescribed processing, and

the plurality of power feed mats includes
a first power feed mat,
a second power feed mat,
a third power feed mat, and
a fourth power feed mat,

in response to the first power feed mat operating as the subject mat,
the fourth power feed mat operates as the first adjacent mat, and
the second power feed mat operates as the second adjacent mat,

in response to the second power feed mat operating as the subject mat,
the first power feed mat operates as the first adjacent mat, and
the third power feed mat operate as the second adjacent mat,

in response to the third power feed mat operating as the subject mat,
the second power feed mat operates as the first adjacent mat, and
the fourth power feed mat operates as the second adjacent mat, and

in response to the fourth power feed mat operating as the subject mat,
the third power feed mat operates as the first adjacent mat, and
the first power feed mat operates as the second adjacent mat.
