cypher - Neo4J: Query nodes where any pair of nodes are connected by a certain number of different relations? -


How to create a Neo4J query:

1) Return all the nodes, where no pair of nodes Are connected to a certain number of different relationships? For example, 2, 3 or 5 different nodes associated with relationships? Therefore, instead of a query returning the nodes associated with unknown number relationships: 

  MATCH (N) - [R] - & gt; (M) Returns N, R, M;   
 In the general case, the query for the sub-graph will appear where no pair of node n & gt; K, n = L or N & L; Relationships?   
 
 
 To find exactly 3 nodes associated with relationships:  
  match (N) - [R * 3] - & gt; (M) Returns N, R, M;   
 To find the nodes associated with many relationships in the category [2..5]:  
  Matt (N) - [R * 2. .5] - & gt; (M) Returns N, R, M;   
 To find the nodes associated with 5 relationships (avoids the lower bound matter of 1, where there is no relationship, i.e., similar to n meter):  < Pre>  Matt (N) - [R * 1] - & gt; (M) Returns N, R, M;   
 To find the nodes associated with at least 2 relationships:  
  Matt (N) - [R * 2 ..] - & gt; (M) returns n, r, m;

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo...
