### GroupCharacterEquationNode.GroupChr property {#groupchr}

Specifies a symbol(default U+23DF). It is strongly recommended to use attribute ChrType to set accent character. Use this property setting if you cannot find the character you need in a known type. It should be noted that this property only accepts one character, and if multiple characters are passed in, only the first character is accepted.

**Type:** String

### GroupCharacterEquationNode.ChrType property {#chrtype}

Specify combining characters by type value. The value of the property is EquationCombiningCharacterType integer constant.

**Type:** Number

### GroupCharacterEquationNode.Position property {#position}

This attribute specifies the position of the character in the object The value of the property is EquationCharacterPositionType integer constant.

**Type:** Number

### GroupCharacterEquationNode.VertJc property {#vertjc}

This attribute, combined with pos of groupChrPr, specifies the vertical layout of the groupChr object. Where pos specifies the position of the grouping character, vertJc specifies the alignment of the object with respect to the baseline. The value of the property is EquationCharacterPositionType integer constant.

**Type:** Number

### GroupCharacterEquationNode.ParentNode property {#parentnode}

Specifies the parent node of the current node

**Type:** EquationNode

### GroupCharacterEquationNode.Type property {#type}

Represents the type of the node. The value of the property is TextNodeType integer constant.

**Type:** Number

### GroupCharacterEquationNode.EquationType property {#equationtype}

Get the equation type of the current node The value of the property is EquationNodeType integer constant.

**Type:** Number

### GroupCharacterEquationNode.StartIndex property {#startindex}

Gets the start index of the characters.

**Type:** Number
